.To a/ZZ whom it may concern:

Beitknown that I, LUTHER PURcnLL Pow- ELL, a citizen of Vthe United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Acetylene- Gas Generators; and I do hereby declare the following to be a full, clear, and exact description of therinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in acetylene-gas generators.

The object of my invention is to improve the construction of this class of apparatus by providing more especially animproved means tom b thereof.

for feeding the carbid to said generator and for clearing out the waste.

Another object is to provide means whereby the rise and fall of the gasometergoverns the fed of the carbid.

With these objects in view my invention consists in the construction and combination of parts,as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevationof my improved gas apparatus. Fig. 2 is a side elevation, partly in section, of the generator, showing the means for feeding the carbid to the water. Fig. 3 is a cross-section of the feeding mechanism on an enlarged scale, parts being removed. Fig. 4 is an enlarged end View of the means operated by the gasometer for effecting the feed. Fig. 5 is an enlarged side View of the same.

a represents the generator, which is simply an open-top vessel provided with an inclined bottom b and an outlet c, closed bya stopcock d. Near the top of this generator is fastened a horizontal partition e, through which the carbid is fed into the generator. In the top eis fastened along sleeve f, which extends nearly to the bottom of the generator and is at right angles to the inclined bot- Through this sleeve runs a rod g, provided with a crank h and handle 't'. The lower end of the rod gis carried in a bearing j, secured to the center of the inclined bottom b. On the rod g j ust above the bearingj are arms or paddles'k for the purpose of agitating the water and carbid fed thereto and for driving the hydrate of lime obtained by the Vdecomposition of the carbid down to the bottom and out through the opening c when the cock d is opened.

Centrally of the top e is fixed a cylindrical casing Z, shown iu the drawings as made in two parts united together by bolts'm. The upper part of this casing has a iaring mouth n, in which closely fits the carbid-hopper o, which isin the shape of a double cone. The hoppero is provided with a screW-capp,which may be removed for the purpose of filling the hopper with carbid before the generator is started. The hopper o has a bottom which is inclined and partly level, theinclined portion q being provided, so that the carbid will easily feed downward. The level portion r is provided with an aperture s, through which passes the agitator-shaft, and with a second aperture t, larger than the other, through which aperture the carbid is fed to the revolving feeder. This feederu is best shown in Fig. 3. It consists of a cylindrical body having a bottom o and a partition w. The bottom 'n is provided with an aperture for the passage of the agitator-shaft, and the partition w is provided with a similar aperture y, the apertures s, y, and x being of course in line with each other. l 4

The partition w is provided with a number of apertures e'. Four of these apertures are shown in the drawings; but it is obvious that any number may be used. From the apertures a pipes l extend downwardly through the bottom c, and'to the bottom of each pipe is pivoted a movable valve 2. One end ofv each ofthese valves is provided with a downwardly-projecting arm 3. In the lower end of each arm is pivoted a roller 4. The casing or pipe lis provided with a partition 5,which partition has an aperture 6 for the reception of the bearing for the agitator-shaft and a larger aperture 7 communicating with the pipe 8, which dares outwardly at its lower end and delivers in to the top of the generator. The pipe 8 is somewhat larger than the pipes 1, which pipes l deliver into said pipe Sas Vthey in turn are brought over said pipe,

the movable valves dropping and discharging the carbid contained in the pipe l into the pipe 8 when the two are in the same straight line. The pipe S is also provided with an inclined plate 9, against which each of the rollers 4 strikes in turn after the corresponding valve 2 has been opened, bringing said valves up to their closed position as the feederurevolves. This revolution is effected in the following manner: The feeder tt is supported on the agitator-shaft 10 and is firmly fixed thereto. This agitator-shaft is supported in bearings in the apertures 6 and s. The lower end of the agitator is provided with a bevel gear-wheel 1l, which meshes with a similar wheel 12 on the shaft 13, which shaft is journaled in a bearing 14, carried by the pipe 8 and in another bearing 15, carried bythe arm 16, which is fastened to the casing a and extends upwardly therefrom.

On the shaft 13 is fixed, by means of a setscrew 17, a toothed wheel 18, which is engaged by a curved pawl 19, carried by a vibrating arm 20, which arm is also fastened to the shaft 14. The arm 2O extends some distance beyond the toothed Wheel 18 and is provided with a heavy weight 21, which normally tends to bring the arm 20 into a vertical position, the pawl during such movement merely slipping over the teeth of the wheel 20.

22 representsa pin provided with a perforated end with which the rod from the gasometer-bell engages to operate the feeder by the rise and fall of\ the bell.

23 represents the gasometer provided with a service-pipe 24 and an inlet-pipe 25, connecting the generator with the gasometer. The gasometer is provided with a horizontal partition 27 near its bottom, forming a chamber which is adapted to be partially filled with water.

28 represents a vertical partition dividing this chamber into two parts. The pipe 25 after entering the gasometer is closed at one end and provided with a number of perforations 26, whereby the gas generated is forced to travel upwardly through the water, thereby washing it.

- the pipe 33, passes through the pipe 35, and

finally escapes into the atmosphere through the branch pipe 36.

37 represents an open-ended drain-pipe attached to the service-pipe 24.

38 represents a guiding-frame for the bell, which is adjustably secured by means of pins 39 in projections 40, extending from the tank.

41 represents the ordinary guide-pulleys attached to 'the bell, and 42 is a rigid bent arm or crane attached to the top 'of the bell. To this arm is attached a rod 44 by means of a pivot 43. The rod 44 carries a stop 45, which by means of the set-screw 46 may be adjusted upon the rod 44. The rod 44 passes downwardly through the perforated pin or projection 22. It is obvious from the construction described that the fall of the bell by means of the stop 45 will operate the feeder, bringing the ratchet devices into the position, for example, shown in Fig. 4. As the bell rises the ratchet devices are restored to their original positions by the weight 21.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
